<p>Also, <span class="user-mention" data-user-id="131694">@scalexm</span>, we talked about this in some detail aroun the all hands, right? <a href="https://github.com/rust-lang-nursery/chalk/pull/206/" target="_blank" title="https://github.com/rust-lang-nursery/chalk/pull/206/">https://github.com/rust-lang-nursery/chalk/pull/206/</a> I'm inclined to just merge this PR right now..?</p>

<p><span class="user-mention" data-user-id="116009">@nikomatsakis</span> btw as I said somewhere else some time ago, the proof for « soundness of implied bounds for traits » without considering implied bounds for types is actually quite simple</p>

<p>And I now understand why the fix I made make the whole setup sound including implied bounds for types</p>

<p><span class="user-mention" data-user-id="131694">@scalexm</span> yep -- so one of the things I want to be doing in this WG is to setup a regular "Design slot"</p>

<p>I was thinking that implied bounds would be a great thing to talk over</p>
